Honolulu

Honolulu is the capital and most populous city of the U.S. state of Hawaii, which is in the Pacific Ocean. An unincorporated city, it is the county seat of the consolidated City and County of Honolulu, situated along the southeast coast of the island of Oʻahu, and is the westernmost and southernmost major U.S. city. Honolulu is Hawaii's main gateway to the world. It is also a major hub for business, finance, hospitality, and military defense in both the state and Oceania. The city is characterized by a mix of various Asian, Western, and Pacific cultures, reflected in its diverse demography, cuisine, and traditions.

Honolulu is Hawaiian for "sheltered harbor" or "calm port"; its old name, Kou, roughly encompasses the area from Nuʻuanu Avenue to Alakea Street and from Hotel Street to Queen Street, which is the heart of the present downtown district. The city's desirability as a port accounts for its historical growth and importance in the Hawaiian archipelago and the broader Pacific region. Honolulu has been the capital of the Hawaiian Islands since 1845, firstly of the independent Hawaiian Kingdom, and since 1898 of the U.S. territory and state of Hawaii. The city gained worldwide recognition following the Empire of Japan's attack on nearby Pearl Harbor on December 7, 1941, which prompted the entry of the U.S. into World War II; the harbor remains a major U.S. Navy base, hosting the United States Pacific Fleet, the world's largest naval command.

Hawaii is the only state with no incorporated places below the county level. The U.S. Census Bureau recognizes the approximate area commonly referred to as the "City of Honolulu" as the Urban Honolulu census-designated place. As of the 2020 U.S. Census, the population of Honolulu was 350,964. The Urban Honolulu Metropolitan Statistical Area had 1,016,508 residents in 2020. With over 300,000 residents, Honolulu is the most populous Oceanian city outside Australasia.

Honolulu's favorable tropical climate, rich natural scenery, and extensive beaches make it a popular global destination for tourists. With over 711,000 visitors as of 2022, Honolulu is the tenth-most visited city in the United States after New York City, Miami, Orlando, Los Angeles, San Francisco, Las Vegas, Washington, D.C., Chicago, and Boston.

History
Evidence of the first settlement of Honolulu by the original Polynesian migrants to the archipelago comes from oral histories and artifacts. These indicate that there was a settlement where Honolulu now stands in the 11th century. After Kamehameha I conquered Oʻahu in the Battle of Nuuanu at Nuuanu Pali, he moved his royal court from the Island of Hawaiʻi to Waikiki in 1804. His court relocated in 1809 to what is now downtown Honolulu. The capital was moved back to Kailua-Kona in 1812.

In November 1794, Captain William Brown of Great Britain was the first foreigner to sail into what is now Honolulu Harbor. More foreign ships followed, making the port of Honolulu a focal point for merchant ships traveling between North America and Asia. The settlement grew from a handful of homes to a city in the early 19th century after Kamehameha I chose it as a replacement for his residence at Waikiki in 1810.

In 1845, Kamehameha III moved the permanent capital of the Hawaiian Kingdom from Lahaina on Maui to Honolulu. He and the kings who followed him transformed Honolulu into a modern capital, erecting buildings such as St. Andrew's Cathedral, Iolani Palace, and Aliiōlani Hale. At the same time, Honolulu became the islands' center of commerce, with descendants of American missionaries establishing major businesses downtown.

Despite the turbulent history of the late 19th century and early 20th century—such as the overthrow of the Hawaiian monarchy in 1893, Hawaii's annexation by the U.S. in 1898, a large fire in 1900, and the Japanese attack on Pearl Harbor in 1941—Honolulu remained the Hawaiian Islands' capital, largest city, and main airport and seaport.

An economic and tourism boom following statehood brought rapid economic growth to Honolulu and Hawaii. Modern air travel brings,, 7.6 million visitors annually to the islands, with 62.3% entering at Honolulu International Airport. Today, Honolulu is a modern city with numerous high-rise buildings, and Waikiki is the center of the tourism industry in Hawaii, with thousands of hotel rooms.

Geography


According to the United States Census Bureau, the Urban Honolulu CDP has an area of 177.2 km2, of which 20.5 km2, or 11.56%, is water.

Honolulu is the remotest major U.S. city and one of the remotest cities in the world. The closest location in mainland U.S. is the Point Arena Lighthouse in northern California, at 2045 nmi. (Nautical vessels require some additional distance to circumnavigate Makapuu Point.) The closest major city is San Francisco, California, at 2397 mi. Some islands off the Mexican coast and part of the Aleutian Islands of Alaska are slightly closer to Honolulu than the mainland.

The volcanic field of the Honolulu Volcanics is partially inside the city.

Neighborhoods, boroughs, and districts

 * Downtown Honolulu is Hawaii's financial, commercial, and governmental center. On the waterfront is Aloha Tower, for many years Hawaii's tallest building. The tallest building is now the 438 ft First Hawaiian Center, on King and Bishop Streets. The downtown campus of Hawaiʻi Pacific University is also there.
 * The Arts District Honolulu, both downtown and in Chinatown, is on Chinatown's eastern edge. It is a 12-block area bounded by Bethel & Smith Streets and Nimitz Highway and Beretania Street—home to numerous arts and cultural institutions. It is within the Chinatown Historic District, which includes the former Hotel Street Vice District.
 * The Capitol District is the eastern part of Downtown Honolulu. It is the current and historic center of Hawaii's state government, incorporating the State Capitol, Iolani Palace, Honolulu Hale (City Hall), State Library, and the statue of King Kamehameha I, along with numerous government buildings.
 * Kakaʻako is a light-industrial district between Downtown and Waikiki that has seen a large-scale redevelopment effort in the past decade. It is home to two major shopping areas, Ward Warehouse and Ward Center. The Howard Hughes Corporation plans to transform Ward Centers into Ward Village over the next decade. The John A. Burns School of Medicine, part of the University of Hawaiʻi at Mānoa, is also there. A memorial to the Ehime Maru Incident victims is at the Kakaʻako Waterfront Park.
 * Ala Moana is a district between Kakaʻako and Waikiki and the home of Ala Moana Center, the "world's largest open-air shopping center" and Hawaii's largest shopping mall. Ala Moana Center has over 300 tenants and is very popular with tourists. Also in Ala Moana is the Honolulu Design Center and Ala Moana Beach Park, Honolulu's second-largest park.
 * Waikiki is Honolulu's tourist district, between the Ala Wai Canal and the Pacific Ocean next to Diamond Head.

Climate
Honolulu experiences a hot semi-arid climate (Köppen classification BSh), with a mostly dry summer season, due to a rain shadow effect. Despite temperatures that meet the tropical threshold of all months having a mean temperature of 64.4 °F (18.0 °C) or higher, the city receives too little precipitation to be classified as tropical.

Temperatures vary little throughout the year, with average high temperatures of 80 – and average lows of 65 –. Nevertheless, there are slight seasons. The "winter" months from December to March can occasionally see lows fall below 64 °F, whereas the "summer" from June to September can get a limited number of hot days achieving 90 °F or higher. This occurs on an average of only 32 days annually, with lows in the upper 50s °F (14–15 °C) once or twice a year. The highest recorded temperature was 95 °F on September 19, 1994, and August 31, 2019. The lowest recorded temperature was 52 °F on February 16, 1902, and January 20, 1969.

The annual average rainfall is 16.41 in, which mainly occurs from October through early April, with very little rainfall in the summer. However, both seasons experience a similar number of rainy days. Light showers occur in summer, while heavier rain falls during winter. Honolulu has an average of 278 sunny days and 89.2 rainy days per year.

Although the city is in the tropics, hurricanes are quite rare. The last recorded hurricane that hit near Honolulu was Category 4 Hurricane Iniki in 1992. Tornadoes are also uncommon and occur about every 15 years. Waterspouts off the coast are also uncommon, hitting about every five years.

Honolulu falls under the USDA 12b Plant Hardiness zone.

The average temperature of the sea ranges from 75.7 °F in March to 80.4 °F in September.

2020 census
The population of Honolulu is 350,964 as of the 2020 U.S. Census, making it the 55th largest city in the U.S. The city's population was 337,256 at the 2010 U.S. Census.

The residential neighborhood of East Honolulu is considered a separate census-designated place by the Census Bureau but is generally considered part of Honolulu's urban core. The population of East Honolulu was 50,922 as of 2020, increasing Honolulu's core population to over 400,000.

In terms of race (including Hispanics in the racial counts), 54.8% were Asian, 17.9% were White, 1.5% were Black or African American, 0.2% were Native American or Alaska Native, 8.4% were Native Hawaiian and Other Pacific Islander, 0.8% were from "some other race", and 16.3% were from two or more races. Separately, Hispanic and Latino residents of any race made up 5.4% of the population. In 1970, the Census Bureau reported Honolulu's population as 33.9% white and 53.7% Asian and Pacific Islander.

Asian Americans are the majority of Honolulu's population. The Asian ethnic groups are Japanese (19.9%), Filipinos (13.2%), Chinese (10.4%), Koreans (4.3%), Vietnamese (2.0%), Indians (0.3%), Laotians (0.3%), Thais (0.2%), Cambodians (0.1%), and Indonesians (0.1%).

Pacific Islander Americans are 8.4% of Honolulu's population. The Pacific Islander ethnic groups are people solely of Native Hawaiian ancestry (3.2%), Samoan Americans made up 1.5% of the population, Marshallese people make up 0.5%, and Tongan people comprise 0.3%. People of Guamanian or Chamorro descent made up 0.2% of the population and numbered 841.

Metropolitan Honolulu, which encompasses all of Oahu island, had a population of 953,207 as of the 2010 U.S. Census and 1,016,508 in the 2020 U.S. Census, making it the 54th-largest metropolitan area in the United States.

Economy


The largest city and airport in the Hawaiian Islands, Honolulu acts as a natural gateway to the islands' large tourism industry, which brings millions of visitors and contributes $10 billion annually to the local economy. Honolulu's location in the Pacific also makes it a large business and trading hub, particularly between the East and the West. Other important aspects of the city's economy include military defense, research and development, and manufacturing.

Among the companies based in Honolulu are:


 * Alexander & Baldwin
 * Bank of Hawaii
 * Central Pacific Bank
 * First Hawaiian Bank
 * Hawaii Medical Service Association
 * Hawaii Pacific Health
 * Hawaiian Electric Industries
 * Matson Navigation Company
 * The Queen's Health Systems

Hawaiian Airlines, Island Air, and Aloha Air Cargo are headquartered in the city. Until it dissolved, Aloha Airlines was headquartered in the city. At one time Mid-Pacific Airlines had its headquarters on the property of Honolulu International Airport.

In 2009, Honolulu had a 4.5% increase in average rent, maintaining it in the second most expensive rental market among 210 U.S. metropolitan areas. Similarly, the general cost of living, including gasoline, electricity, and most foodstuffs, is much higher than on the U.S. mainland, because the city and state have to import most goods. One 2014 report found that cost of living expenses were 69% higher than the U.S. average.

Since the only national banks in Hawaii are all local, many visitors and new residents must get accustomed to different banks. First Hawaiian Bank is Hawaii's largest and oldest bank, headquartered at the First Hawaiian Center, the state's tallest office building.

Natural museums
The Bishop Museum is Honolulu's largest museum. It has the state's largest collection of natural history specimens and the world's largest collection of Hawaiiana and Pacific culture artifacts. The Honolulu Zoo is Hawaii's main zoological institution, while the Waikiki Aquarium is a working marine biology laboratory. The Waikiki Aquarium partners with the University of Hawaiʻi and other universities worldwide. Established for appreciation and botany, Honolulu is home to several gardens: Foster Botanical Garden, Liliuokalani Botanical Garden, Walker Estate, among others.

Performing arts
Established in 1900, the Honolulu Symphony is the second-oldest U.S. symphony orchestra west of the Rocky Mountains. Other classical music ensembles include the Hawaii Opera Theatre. Honolulu is also a center for Hawaiian music. The main music venues include the Hawaii Theatre, the Neal Blaisdell Center Concert Hall and Arena, and the Waikiki Shell.

Honolulu also includes several venues for live theater, including the Diamond Head Theatre and Kumu Kahua Theatre.

Visual arts
The Honolulu Museum of Art has Hawaii's largest collection of Asian and Western art. It also has the largest collection of Islamic art, housed at the Shangri La estate. Since the merger of the Honolulu Academy of Arts and The Contemporary Museum, Honolulu (now called the Honolulu Museum of Art Spalding House) in 2011, the museum is also the state's only contemporary art museum. The contemporary collections are housed at main campus (Spalding House) in Makiki and a multi-level gallery in downtown Honolulu at the First Hawaiian Center. The museum hosts a film and video program dedicated to arthouse and world cinema in the museum's Doris Duke Theatre, named for the museum's historic patroness Doris Duke.

The Hawaii State Art Museum (also downtown) has pieces by local artists as well as traditional Hawaiian art. The museum is administered by the Hawaii State Foundation on Culture and the Arts.

Honolulu also annually holds the Hawaii International Film Festival (HIFF). It showcases some of the best films from producers all across the Pacific Rim and is the largest "East meets West" style film festival of its sort in the United States.

Fans of spectator sports in Honolulu generally support the football, volleyball, basketball, rugby union, rugby league, and baseball programs of the University of Hawaiʻi at Mānoa. High school sporting events, especially football, are especially popular.

Honolulu has no professional sports teams, with any prospective teams being forced to conduct extremely long travels for away games in the continental states. It was the home of the Hawaii Islanders (Pacific Coast League, 1961–87), The Hawaiians (World Football League, 1974–75), Team Hawaii (North American Soccer League, 1977), and the Hawaiian Islanders (af2, 2002–04).

The NCAA football Hawaii Bowl is played in Honolulu. Honolulu also hosted the NFL's annual Pro Bowl each February from 1980 to 2009.

Highways
Honolulu has been ranked as having the nation's worst traffic congestion, beating former record holder Los Angeles. Drivers waste on average over 58 hours per year on congested roadways. The following freeways, part of the Interstate Highway System serve Honolulu:


 * I-H1.svg Interstate H-1, western terminous is at Kapolei where you can connect to the Farrington Highway. The H-1 passes Hickam Air Force Base and Honolulu International Airport, runs through Pearl City before heading downtown into Honolulu continues eastward through Makiki and Kaimuki, ending at Waialae/Kahala and start of the Kalanianole Highway.
 * I-H201.svg Interstate H-201—also known as the Moanalua Freeway and sometimes numbered as its former number, Hawaii State Route 78—connects two points along H-1: at Aloha Stadium and Fort Shafter. Close to H-1 and Aloha Stadium, H-201 has an exchange with the western terminus of Interstate H-3 to the windward side of Oahu (Kaneohe). This complex of connecting ramps, some directly between H-1 and H-3, is in Halawa.
 * I-H2.svg Interstate H-2 Connects at a junction near Waipau and Pearl City with the H-1 freeway. The H-2 freeway will take you up to Schofield barracks before ending at Wahiawa where it connect to the north shore.
 * I-H3.svg Interstate H-3 Connects at a junction near Halawa Heights. This interstate highway will take you from Halawa heights through the Ko'olau Range to Kaneohe. Its final termination is at Marine Corps Base Hawaii. Exit 15 is the last exit before entering Marine Corps Base Hawaii.

Other major highways that link Honolulu CCD with other parts of the Island of Oahu are:
 * HI-61.svg Pali Highway, (State Route 61), crosses north over the Koʻolau range via the Pali Tunnels to connect to Kailua and Kaneohe on the windward side of the Island.
 * HI-63.svg Likelike Highway, (State Route 63), also crosses the Koʻolau to Kaneohe via the Wilson Tunnels.

 * Farrington Highway, State Route 93 runs western leeward Oahu from Kaena Point through Waianae and Makaha before the start of the H-1. State Rte 930 starts east to west in the north shore connecting you from Wailua to Kaena Point

Like most major American cities, the Honolulu metropolitan area experiences heavy traffic congestion during rush hours, especially to and from the western suburbs of Kapolei, Ewa Beach, Aiea, Pearl City, Waipahu, and Mililani.

There is a Hawaii Electric Vehicle Demonstration Project (HEVDP).

Honolulu Authority for Rapid Transportation
In November 2010, voters approved a charter amendment to create a public transit authority to oversee the planning, construction, operation and future extensions to Honolulu's rail system, now known as Skyline. The Honolulu Authority for Rapid Transportation (HART) has a 10-member board of directors, with three members appointed by the mayor, three selected by the Honolulu City Council, and the city and state transportation directors.

The opening of the first phase of the Skyline was delayed until 2023, as HART canceled the initial bids for the first nine stations, rebid the work as three packages of three stations each, and allowed more time for construction in the hope that increased competition on smaller contracts would drive down costs; initial bids ranged from $294.5 million to $320.8 million, far surpassing HART's budget of $184 million.

Bus
Established by former Mayor Frank F. Fasi as the replacement for the Honolulu Rapid Transit Company (HRT), Honolulu's TheBus system was honored in 1994–95 and 2000–01 by the American Public Transportation Association as "America's Best Transit System". TheBus operates 107 routes serving Honolulu and most major cities and towns on Oʻahu. TheBus comprises a fleet of 531 buses, and is run by the nonprofit corporation Oʻahu Transit Services in conjunction with the city Department of Transportation Services. , Honolulu was ranked fourth for highest per-capita use of mass transit in the United States.

Para-transit Options

The island also features TheHandi-Van, for riders who require para-transit operations. To be eligible for this service, riders must meet the requirements of the Americans with Disabilities Act (ADA). TheHandi-Van has a fare of $2 and is available from 4am to 1am. There is a 24-hour service within 3/4 of a mile of TheBus route 2 and route 40. TheHandi-Van comprises a fleet of 160 buses. The parantransit branch also runs Human Services Transportation Coordination (HSTCP), which mainly provides transportation for people with disabilities, older adults, and people with limited incomes, assisted by the Committee for Accessible Transportation (CAT). Both organizations work together to provide transportation for elderly and persons with disabilities.

Rail
Honolulu has no urban rail transit system, though electric street railways were operated in Honolulu by the now-defunct Honolulu Rapid Transit Company before World War II. Predecessors to the Honolulu Rapid Transit Company were the Honolulu Rapid Transit and Land Company (began 1903) and Hawaiian Tramways (began 1888).

The City and County of Honolulu is constructing a 20 mi rail transit line that will connect Honolulu with cities and suburban areas near Pearl Harbor and in the Leeward and West Oahu regions. Skyline aims to alleviate traffic congestion for West Oʻahu commuters while being integral in the westward expansion of the metropolitan area. The project has been criticized for its cost, delays, and potential environmental impacts, but the line is expected to have large ridership. The line's first segment connects East Kapolei and Aloha Stadium and opened on June 30, 2023.

Bicycle sharing
Since June 28, 2017, Bikeshare Hawaii administers the bicycle sharing program in Oʻahu while Secure Bike Share operates the Biki system. Most Biki stations are between Chinatown/Downtown and Diamond Head, but a 2018 expansion added stations toward the University of Hawaiʻi at Mānoa Campus, Kapiolani Community College, Makiki, and Kalihi area.

Modal characteristics
According to the 2016 American Community Survey (five-year average), 56% of Urban Honolulu residents commuted to work by driving alone, 13.8% carpooled, 11.7% used public transportation, and 8.7% walked. About 5.7% commuted by bike, taxi, motorcycle or other forms of transportation, while 4.1% worked at home.

The city of Honolulu has a high percentage of households without a motor vehicle. In 2015, 16.6% of Honolulu households were car-free, which increased slightly to 17.2% in 2016; by comparison, the United States national average was 8.7% in 2016. Honolulu averaged 1.4 cars per household in 2016, compared to a national average of 1.8.

Public safety
The Honolulu Police Department is the primary law enforcement agency for the city and county of Honolulu and serves the entire Oahu Island. Honolulu Police Department has a mixed fleet of marked patrol cars and unmarked along with a subsidized vehicle program in place. Marked vehicles are white with blue stripes and white lettering HONOLULU POLICE. The Honolulu Police Departments lets officers of a certain rank purchase a private vehicle for police use. Subsidized vehicles are unmarked but have a small blue roof light. Subsidized vehicles can be any make, model, or color, but must follow department rules and guidelines. Honolulu Police and Hawaii County Police on the Big Island are the only departments in the state of Hawaii and the U.S. with subsidized vehicles. Honolulu Police along with other city, county law enforcement in Hawaii uses blue lights for their vehicles. They also keep their cruise blue lights on while on patrol.

The Honolulu Fire Department provides firefighting services and first responder level emergency medical services on Oahu. Emergency medical services at higher levels are provided by the Honolulu Emergency Medical Services. Contrary to most other fire departments, fire trucks in Honolulu are yellow.
